  • Patent number: 7155672
    Abstract: Methods and system for dynamic font subsetting. One or more directives are inserted into electronic content to identify one or more glyph sub-sets needed to display the multiple characters in one or more desired languages for electronic content. A directive identifies a glyph sub-set including set of glyphs identified in the electronic content and an encoding scheme used to encode the set of glyphs. The glyph sub-set identifies only those glyphs needed to display the electronic content. When electronic content with the one or more directives is processed the one or more directives are identified. If the electronic device does not have the glyph sub-sets needed to display the electronic content, requests are sent to an intermediate network device to obtain glyph sub-sets. These method and system may allow an electronic device with limited resources, such as a wireless telephone, personal digital assistant, network appliance, set-top box, etc.

  • Patent number: 5818605
    Abstract: Method and apparatus for high resolution sensing of engraving stylus movement for dynamic control of an engraving machine while engraving, improved calibration and as a tool used to assist in selecting acceptable gravure cylinders and improving the manufacturing process of making gravure cylinders is described. A variety of sensors are described in conjunction with measuring engraving stylus movement, specifically, sensors that measure small changes in capacitance, resistance, impedance, optical reflections, optical interference patterns, induced eddy currents and voltages induced in a two-material piezoelectric rod which corresponding to positional changes of the engraving stylus.

  • Patent number: 4763207
    Abstract: There is disclosed herein a method of and system for reproducing an analog signal using digital techniques. The system includes means for encoding the analog signal in digital form and means for decoding the encoded analog signal. The encoding means includes means for detecting the upper bandwidth limit of the input analog signal during each of a plurality of successive sample intervals. Means coupled to the detecting means are included for sampling the input analog signal at a sampling rate determined in accordance with the detected upper bandwidth limits to derive a series of voltage levels which together define a sampled approximation of the input analog signal. Means are coupled to the sampling means for converting each voltage level and the sampling rate at which such voltage level was derived into digital signals.
